The Twike (a portmanteau of the words twin and bike) is a human-electric hybrid vehicle (HEHV) designed to carry two passengers and cargo. Essentially a velomobile with an electrical hybrid engine, it can be driven in electric-only mode or electric + pedal power mode. Pedaling warms the user, making electric heating in winter unnecessary, extends the range of the vehicle but does not substantially add to the vehicle's top speed.

Constructed of lightweight materials such as aluminium (frame) and plastic (shell), the 246 kg (542 lb) (unladen, varying with battery weight) tricycle vehicle first used NiCd batteries, later Li-Mn, LiFePO₄ and LiIon. Typically ranges reach from 50 to over 500 km depending on battery size, type, status on one side and speed and altitude profile and load on the other. Energy is reclaimed while driving through regenerative braking, and load is removed from the electric system by use of the pedalling system which transfers its input directly to the drivetrain (i.e., both systems operate in parallel, not in series).

🔗 Ancient Egypt 🔗 Board and table games

Senet (or senat) is a board game from ancient Egypt, whose original rules are the subject of conjecture. The oldest hieroglyph resembling a senet game dates to around 3100 BC. The full name of the game in Egyptian is thought to have been zn.t n.t ḥˁb, meaning the "game of passing".

In 1995, on the occasion of the 100th anniversary of cinema, the Vatican compiled a list of 45 "great films". The 45 movies are divided into three categories: religion, values, and art.

A mount of piety is an institutional pawnbroker run as a charity in Europe from Renaissance times until today. Similar institutions were established in the colonies of Catholic countries; the Mexican Nacional Monte de Piedad is still in operation.

The institution originated in Italy in the fifteenth century, where it gave poor people access to loans with reasonable interest rates. It used funds from charitable donors as capital, and made loans to the poor so they could avoid going to exploitative lenders. Borrowers offered valuables as collateral, making the mount of piety more like a pawn shop than a bank.

The Viterbi algorithm is a dynamic programming algorithm for obtaining the maximum a posteriori probability estimate of the most likely sequence of hidden states—called the Viterbi path—that results in a sequence of observed events, especially in the context of Markov information sources and hidden Markov models (HMM).

The algorithm has found universal application in decoding the convolutional codes used in both CDMA and GSM digital cellular, dial-up modems, satellite, deep-space communications, and 802.11 wireless LANs. It is now also commonly used in speech recognition, speech synthesis, diarization, keyword spotting, computational linguistics, and bioinformatics. For example, in speech-to-text (speech recognition), the acoustic signal is treated as the observed sequence of events, and a string of text is considered to be the "hidden cause" of the acoustic signal. The Viterbi algorithm finds the most likely string of text given the acoustic signal.

🔗 Electronic music 🔗 R&B and Soul Music

Woo! Yeah! is a drum break that includes James Brown's ("Woo!") and Bobby Byrd's ("Yeah!") voices which has been widely sampled in popular music, often in the form of a loop. The drum break was performed by John "Jabo" Starks. It originates from the 1972 Lyn Collins recording "Think (About It)", a song written and produced by Brown, and is just one of a few other frequently used breaks contained in the recording, often collectively known as the Think Break.

112 Gripes About the French was a 1945 handbook issued by the United States military authorities to enlisted personnel arriving in France after the Liberation. It was meant to defuse the growing tension between the American military and the locals.

The euphoria of victory over Germany was short-lived, and within months of Liberation, tensions began to rise between the French and the U.S. military personnel stationed in the country, with the former seeing the latter as arrogant and wanting to flaunt their wealth, and the latter seeing the former as proud and resentful. Fights were breaking out more often, and fears were raised, even among high officials, that the situation might eventually lead to a breakdown of civil order.

Set out in a question-and-answer format, 112 Gripes about the French posed a series of well-rehearsed complaints about the French, and then provided a common-sense rejoinder to each of them — the aim of the authors being to bring the average American soldier to a fuller understanding of his hosts.

It has recently been republished in the United States (ISBN 1-4191-6512-7), and in France under the title "Nos amis les Français" ("Our friends the French"), ISBN 2-7491-0128-X.

🔗 Mathematics

A mathematical coincidence is said to occur when two expressions with no direct relationship show a near-equality which has no apparent theoretical explanation.

For example, there is a near-equality close to the round number 1000 between powers of 2 and powers of 10:

${\displaystyle 2^{10}=1024\approx 1000=10^{3}.}$

Some mathematical coincidences are used in engineering when one expression is taken as an approximation of another.

"The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information" is one of the most highly cited papers in psychology. It was published in 1956 in Psychological Review by the cognitive psychologist George A. Miller of Harvard University's Department of Psychology. It is often interpreted to argue that the number of objects an average human can hold in short-term memory is 7 ± 2. This has occasionally been referred to as Miller's law.

Depopulation of cockroaches in post-Soviet states refers to observations that there has been a rapid disappearance of various types of cockroaches since the beginning of the 21st century in Russia and other countries of the former USSR. Various factors have been suggested as causes of the depopulation.
